Application filed August 19, 1812. 'Serial No. 715,895.

To all whom it may concern.

lie it known that I, ALBERT A. lit/[Ao- State of llflassachusetts, have, invented certain improvements in lVork-Supports, of which the following description, in. connection withthe accompanying draw-g ings, is a specification, like reference char-; acters on the drawings indicating like parts in the: several figures.

This invention relates to shoe machines and particularly to work rest, as for on ample, a toe rest and is shown by way of eremplificationas embodied in the toe rest, ota bed lasting; machine.

In machines of this type the last is sup ported by a last pin which enters the lllllll'k bio of the last and by a toe rest which sup-.

sorts the toe portion of the shoe from beneath and is usually so arranged that it may be elevated to force the shoe into the heel band 1nthe-operat1on oi? yacking the shoe.

in certain types oi: modern lasts one side of the toe portion is considerably thicker than the other side to correspond to the shape of the foot, the toe portion of which is. thicker along; the side Where the great toe is located than along the opposite side. To support properly the right and left toes of such lasts, it is desirable to have a rest which will adjust itself to accommodate the varying thicknesses ofthetwo sides of the last and will rest evenly upon the transverse portion of the toe without bearing too heavily atthe thickest part. At the same time a rest must be provided which will hold the toe with sufficient security to prevent displacement of the shoe by the action of the wipers and which will not scratch or mar the leather of the shoe in case the shoe is rubbed over the rest during the jacking or the lasting operations.

It is the object of the present invention to provide a rest which will possess the above and other advantages, and as a feature of the invention a rest is provided which has a work engaging surface and is arranged to rock about an axis extending longitudinally of the shoe and preferably through said .work engaging surface or an adjacent porcomposed of resilient material capable of conforming to inequalities or irregularities in the engaging surface of the shoe and supporting it equally at all points en ased thereby. Preferably and as shown, the shoe engaging; portion comprises a block of soft rubber in the term of the seg'inentof a cylinder which is supported in a similarly shaped box or casing, the ceslng being mounted on the toe post for sliding lnovement on its cylindrical surface. These and other features of the invention will appear more fully from the following detailed description when read in connection with the accompanying}; drawing and from the appended claims.

Figure 1 is a perspective view of the toe head of a bed lasting; machine provided with a toe rest embodying the present invention; Fig. 2 is a sectional view showing; the toe rest in side elevation; 3 is a transverse sectional view of the rest.

Referring to Fig. 1, A indicates the toe head of a bed lasting machine and B the wipers which are operated by the lever C. fit I) is indicated a portion of a slide upon which the toe post rests and which is actuated vertically to raise the toe restin the operation of jacking the shoe. The toe post. 2 is mounted for vertical movement in a sleeve 4: formed on the toe'head and is provided with a slot 6 which is engaged by the end of a screw 8 to prevent turning of the post about its longitudinal axis while vertical movement thereof is permitted. A screw 10 furnishes height adjustment for the post. p

Upon the upper end of the post 2 is a head 12 with which a block M has dovetailed connection to permit movement of the block 14 longitudinally of the shoe relatively to the head 12. This movement is limited by a pin 16, Fig. .3, and the block 14- is resiliently held in central position over the post 2 by springs 18 and 20, the spring 18 resting between the pin 16 and the end of a slot 22 in the under face of the dovetailed guide 01 the block 14L, and the spring 20 resting between the pin 16 and a plate 2% which covers the end of the slot 22 and is secured to the block 14- at26. As will be readily observed, the parts may be separated by the removal of the plate 24.

In the upper portion of the block 1% is a cavity in the shape of a segment of a cylinder and slots 28 concentric with the eurva ture of the cylinder are formed in the walls of the cavity. A box 30 also in the form of the segment of a cylinder rests in the cavity of the block 14: and carries, in turn, a segment or crescent-shaped block 32 of suitable resilient material, as for example, soft rubber. The rubber segment 32 is held in the box 30 and the box 30 is held in the cavity of the block 14 by a pin 3% which passes through holes in the segment 32 and in the box 30 and through the slots 28 in the block 14. The slots 28 permit the box to rock relatively to the block ll. To hold the pin in position, the end thereof is slotted and a but ton 36 is pivoted in the slot at a point displaced longitudinally from the center of the button 36. By this arran ement one end of the button 36 is heavier than the other and tends to remain in the position shown, thereby preventing the removal of the pin 34:. When the button 36 is turned into a position of longitudinal alinement with the pin 34, the pin may be removed and the box 30 and segment 32 taken out for renewal or replacement.

The se ment 32 may be made of either black or red rubber, the black being preferably used for black shoes and the red for russet or white shoes. The arrangement described furnishes a convenient means for re moving a segment or pad of one kind and substituting another.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent of the United States is 1. In a machine of the class described, the combination of a toe post, a block mounted on the post, a segmental box mounted for movement in said block, and a pad in the box to engage and support the toe portion of a shoe.

2. In a machine of the class described, a

toe post, a block on the post having a recess therein formed as a segment of a cylinder, and a cylindrical segment adapted to fit freely in said block and having an approximately straight side by which to support a shoe toe.

3. A device of the class described, having, in combination, a block hollowed as a segment of a cylinder, 21 segment-shaped box adapted to fit said hollow, and a block of resilient material seated in said box, and adapted to support the toe of a shoe.

a. A device of the class described having, in combination, a toe post, a block mounted thereon for movement longitudinally of a shoe, resilient means for holding the block centrally over the post, and a segmental pad mounted with its curved side lowermost to move freely in said block transversely of the shoe.

5. A device of the class described having, in combination, a toe post, a block thereon, a segmental box mounted in said block for free sliding movement on its cylindrical surface, a resilient pad mounted in said box, a pin passing through the pad and box to secure them together, and through slots in the block, said slots permitting movement of the pad and box relatively to the block.

6. A device of the class described comprising a block 14, a box 30 seated therein, a pad 32 in the box, a pin 34 passing through the pad 32 and box 30 and through slots 28 in the block 14: and provided with the turn button 36, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
